+  nominal_datatype2 does the following things in order:
+
+Parser.thy/raw_nominal_decls
+  1) define the raw datatype
+  2) define the raw binding functions 
+
+Perm.thy/define_raw_perms
+  3) define permutations of the raw datatype and show that the raw type is 
+     in the pt typeclass
+      
+Lift.thy/define_fv_alpha_export, Fv.thy/define_fv & define_alpha
+  4) define fv and fv_bn
+  5) define alpha and alpha_bn
+
+Perm.thy/distinct_rel
+  6) prove alpha_distincts (C1 x \<notsimeq> C2 y ...)             (Proof by cases; simp)
+
+Tacs.thy/build_rel_inj
+  6) prove alpha_eq_iff    (C1 x = C2 y \<leftrightarrow> P x y ...)
+     (left-to-right by intro rule, right-to-left by cases; simp)
+Equivp.thy/prove_eqvt
+  7) prove bn_eqvt (common induction on the raw datatype)
+  8) prove fv_eqvt (common induction on the raw datatype with help of above)
+Rsp.thy/build_alpha_eqvts
+  9) prove alpha_eqvt and alpha_bn_eqvt
+     (common alpha-induction, unfolding alpha_gen, permute of #* and =)
+Equivp.thy/build_alpha_refl & Equivp.thy/build_equivps
+ 10) prove that alpha and alpha_bn are equivalence relations
+     (common induction and application of 'compose' lemmas)
+Lift.thy/define_quotient_types
+ 11) define quotient types
+Rsp.thy/build_fvbv_rsps
+ 12) prove bn respects     (common induction and simp with alpha_gen)
+Rsp.thy/prove_const_rsp
+ 13) prove fv respects     (common induction and simp with alpha_gen)
+ 14) prove permute respects    (unfolds to alpha_eqvt)
+Rsp.thy/prove_alpha_bn_rsp
+ 15) prove alpha_bn respects
+     (alpha_induct then cases then sym and trans of the relations)
+Rsp.thy/prove_alpha_alphabn
+ 16) show that alpha implies alpha_bn (by unduction, needed in following step)
+Rsp.thy/prove_const_rsp
+ 17) prove respects for all datatype constructors
+     (unfold eq_iff and alpha_gen; introduce zero permutations; simp)
+Perm.thy/quotient_lift_consts_export
+ 18) define lifted constructors, fv, bn, alpha_bn, permutations
+Perm.thy/define_lifted_perms
+ 19) lift permutation zero and add properties to show that quotient type is in the pt typeclass
+Lift.thy/lift_thm
+ 20) lift permutation simplifications
+ 21) lift induction
+ 22) lift fv
+ 23) lift bn
+ 24) lift eq_iff
+ 25) lift alpha_distincts
+ 26) lift fv and bn eqvts
+Equivp.thy/prove_supports
+ 27) prove that union of arguments supports constructors
+Equivp.thy/prove_fs
+ 28) show that the lifted type is in fs typeclass     (* by q_induct, supports *)
+Equivp.thy/supp_eq
+ 29) prove supp = fv
